' This invention relates to an improved machine for sterilizing andwashing ice, cream scoops, glasses,-and similar utensils used inassociation with soda fountains.

6 Briefly the invention comprises a. tank, in which a utensil rack ismounted for rotati'on, this rack being constructed to hold the scoo sagainst displacement, and being rotate by a hydraulic motor.

My principal aim is to provide a simple and inexpensive structure ofthis class which is practical, sturdy, eflicient in operation, andcapable of accomplishing the desired results in an efficient manner. v

Other features and advantages of the in vention will become apparentfrom the following description and drawings.

Inthe accompanying drawings, forming a part of this application, and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is a view in section and elevation of the complete machine. IFigure 2 is a top plan 'view with the 25. c0ver of the tank in openposition. 7

Y fliigure 3 is a perspective view of the scoop rac I Figure 4 isa..perspective view. of a portion of the piping, valve controls, andhydraulic motor.

'Referring now to the drawings by reference numerals, it will beobserved that the reference character 1 designates a-casing or tankwhich is referably of the configuration shown in ig. 2. This tank may beconstructed oi, sheet metal, the same being referably open at its topand the open top Being closed by a hinged lid or cover 2. Located insideof the tank, on "the opposite side walls are shelves 3 for supportingglasses and similar articles;

A revolving rack is supported in the tank for rotation. This rack, asbetter shown in Fig. 3 comprises a substantially circular base plate '5,a rotating shaftfi, and a cage for holding the various utensils; Thecage comprises a' multiplicity'of vertically disposed circumferentiallyspaced rods connected with the base plate, and held together bya centralring 8.

Also connected with the uprights, and associated with the ring 8 areupper and lower annular members which are provided with a multiplicityof small rings 9 and 10 respectively.

The base plate 5 is formed with water I water holes 11. The shaft 6 onthe bottom pipe fittings, and couplings arran ed in an 1926." Serial No.116,851.

set' up a strong agitation of the water to I P as v aid in-cleaning theutensilssupported on the rack. a

The vanes act somewhat as baflle plates also, and any water which iscollected there-. beneath, escapes downwardly through the of the baseplate is. mounted for rotation, in the bottom of the casing or tank inan appropriatemanner. In addition, the casing is, in turn, supported ona frame 13 carried by uprights 14. l

Novel means .is disposed beneath the frame and casing for supplyingwater'to the tank and for operating the revolving rack; The meansembodies a plurality of orderly and com act manner, as s own better inFig. 4J1eference being bad to this figure, it will be seen that thismeans comprises 'principall a housing 15 for a'fluid motor 15", (see ig.1).

In this connection, it might be stated that, the shaft 6 on the bottomof the rack extends down and is connected with this rotor. Thus, theseparts operate to provide a hydraulic motor.

Gonnectedto one side of the housing 15 is.a water intake which isconnected through the medium of couplings and pipe fittlngs with controlvalves 17 and 18, located in hot and. cold water supply pipes,- leadingfrom any suitable source of supply.- Lea'd ing from the opposite side ofthe'housing is a discharge neck 19, which is'coupled tov a T-shapedcoupling 20. V

Connected with thefcoupling 20 we findbranchpipes'21 and 22 which are inturn connected with independent control valves 23 and 24. Incidentally,operating rods or stems are provided' for operat' these, valves 23 and24- and are substan it. y provided on their control ends with? 'andgrips 25 and 26. The valve 24 is connected with a water discharge pipe27 on the upper end of which is an elbow 28.

This elbow constitutes a drain and is connected at the bottom of thetank on oneside. Connected to the bottom on an opposite side is asimilar elbow 29, which leads from the .Valve 23. A plug 31 having a hadle 32 is located in the rear compartment 0 the tank as shown in Fig. 1,and serves to control the flow of water from the tank back down throughthe elbow 28 and into the discharge pipe 27 In operation, water underpressure is supplied to each one of the ipes 17 or 18, through theintake 16 o the h draulic motor. The motor is, thus operate whichin turnservesto rotate the rack 4 thru the medium of the shaft 6. When themachine is first started, the valve 24 is closed, while the valve 23 isopened. This allows the water to flow through the coupling 20, the

branch 21, valve 23, and elbow 29, into the tank until the tank issubstantially full of A water.

The rotation of the rack within this water and the agitation of thewater itself caused by the rotation serves to cleanse the articlesupported on the track. When suflicient water is in the tank, forcleaning purposes, the valve 23 is closed. However, at this time, thevalve 24 is now open, allowing the water which is running the hydraulicmotor,

to flow down through the discharge pipe 27.

When however, the water in the tank be comes heavily laden with' greaseand dirt, and it is desired to drain the tank, then the plug 31'islifted, allowing the water to drain 7 downthrough the elbow 28 and intothe pipe 27. Of course the valve 23 is again opened to refill the tank.

If esired, a brush 30 may be suitabl mounted on the central portion ofthe rack to aid in cleaning the utensils. The brush of course, affectsno cleaning-while the rack ,is in rotation, but enables the operator to.scrub off some of the particles of dirt from the utensils,before'thef-are placed upon the rack for agitation in the water.

The construction and operation of the device -will undoubtedlybe clearby considering the description in connection with the drawings.Therefore, a more lengthy de scription is deemed unnecessary.
